From Tekno RC:
The NB48 has been carving out its place as the top 1/8th scale nitro buggy for many years now. Through its history, we have continually improved on every aspect of performance and durability. The progression from the NB48 to the NB48.3 evolved through many significant changes, industry firsts, and also hundreds of fine adjustments. With the introduction of the NB48.4, we have once again raised the bar and improved on nearly every aspect of the buggy. This time it took the form of many fine adjustments, but the leap in performance is our most significant yet.

These changes feed into one desire to manufacture the best handling, most consistent, most durable, and highest value kit on the market. We’re confident that our wonderful customers will agree that we have delivered on these goals.
